Changes through time. “Survival of the Fittest”. Evidence that life has changed and is now changing. Fossil Record. Fossils are remains or traces of organisms that lived in the past. Fossil Record. Fossils are usually found in sedimentary rock.

The Rhind papyrus * named after the Scottish Egyptologist Alexander Henry Rhind, who purchased it in 1858 * written around 1650 BC by the scribe Ahmes who copied a document 200 years older * contains mathematical and geometric problems * Uses the value. how do we know?.

Radioisotopic/radiometric dating. Radioisotopic/radiometric dating. Many believe in an old earth, i.e., billions of years old, due to radioisotopic dating. Radioisotopic/radiometric dating. Many believe in an old earth, i.e., billions of years old, due to radioisotopic dating

It takes 5,730 years for HALF of the TOTAL amount of Carbon-14 to decay into Nitrogen-14.

Archaeology of Native North American Sites. Renee B. Walker, Ph.D. Oneonta State College New York. What is Archaeology anyway?. Fossils-Studied by Paleoanthropologists. Preserved remains of creatures from the past. Fossil localities are where fossils are found.

The Carbon Story. The stuff of life All you ever wanted to know but were afraid to ask. Atoms and molecules. The simplest known substances are called “elements” an element has only one type of atom There are 92 naturally occurring elements

Mr. Karns. Biology. Fossils. 17-1 The Fossil Record. Fossils and Ancient Life. What is the fossil record? It is NOT an Elvis Presley record!. Fossils and Ancient Life. Fossils and Ancient Life Paleontologists are scientists who collect and study fossils.

Test Friday!!!!!!!. 10-6 Exponential Growth and Decay. Depreciation Decay y = a ( 1 - r ) t y = ae -kt.

Radioactivity 6. Half Life. Half Life. The half-life of a radioactive substance: • is the time it takes for the number of parent atoms in a sample to halve; • is the time it takes for the count rate from the original substance to fall to half its initial level.

EARTH HISTORY. Chapter 6 review. THREE FUNDAMENTAL PRINCIPLES. 1. UNIFORMITARIANISM :. -The processes that shape the Earth today are the same processes that occurred in the geologic past. “The present is the key to the past”. 2. ORIGINAL HORIZONTALITY.

Origin of Life. Chapter 14. Biogenesis vs. Spontaneous Generation. Biogenesis States that all living things come from other living things Spontaneous generation Early, now disproved, hypothesis that living organisms develop from nonliving material. Francesco Redi’s.

Chapter 32. Geologic History Relative & Absolute Dating. BFRB Pages 245-256. Who’s got the TIME?. RELATIVE TIME - the order or sequence is known, but not the actual date of occurrence. Example - the trilobite fossil is older than the dinosaur fossil

Radioactivity. A. The spontaneous breakdown of an unstable atomic nucleus with the release of radiation. III. Radioactivity. Definition: Unstable isotopes change into different, more stable elements.

§3.3 Logarithmic Functions. The student will learn about:. the logarithmic function,. its properties, and. applications. Introduction. In this section we introduce logarithmic functions, emphasizing the natural logarithm function.

NUCLEAR CHEMISTRY. Rates of Decay & Half Life. Radionuclides have different stabilities and decay at different rates. Integrated Rate Equation. where… A = the amt. of decaying sample remaining at some time, t A o = the amt. of sample present at the beginning

Radioactivity (Exponential Example). Atoms. Atoms are made of protons, electrons and neutrons. Protons and neutrons reside in the middle, or nucleus, and electrons reside in the outer portion of an atom. Atomic Number. The atomic number is the number of protons an element has.

Evolution vs. Science & the Bible (Lesson 7). Part I: The Age of the Earth Part II: Dinosaurs. AGE OF THE EARTH. Dating Rocks and Fossils. The Atom. Fundamental unit of matter Made up of components called subatomic particles Proton (positive charge) Neutron (no electrical charge)

FWC School of Apologetics. An in-depth program that aims to equip believers to give answers for why they believe what they believe. Each class you take is worth one credit. Credits build up to certificates. Bronze Certificate in Biblical Apologetics - 5 Credits

Get a Charge Out of Matter Jeopardy. Final Jeopardy. Category is: Half-lives. Sub-Atomic Awesomeness 100. What particles make up most of the mass of an atom? Answer: Protons & Neutrons. Sub-Atomic Awesomeness 200. What particles can be found in the nucleus of an atom?
